Layback in DaVinci Resolve
The layback is the final step in the post-production process wherein the final sound mix is married with the final color-corrected picture. At CalArts, sound is mixed for 5.1 theatrical surround sound playback, LtRt stereo playback with Dolby Compatibility, and Internet Only stereo for streaming playback. DaVinci Resolve will allow us to create multiple outputs from a single timeline containing all mix files regardless of their format. This process will involve several steps.
- You will create a folder for all the necessary deliverables.
- You will create a Resolve project containing two timelines, one with leader and one without.
- We will be creating 3 different Outputs:
Surround (OriginalResolution/5.1)
Internet (HD/Stereo)
ArchivalMaster (OriginalResolution/5.1+LtRt+Internet)
- If the student requests DVD & Blu-ray assets, please see the Appendix for learning how to make an .m2v file for DVD, an H.264 file for Blu-ray, and an .ac3 audio file.
Preparing for the Layback
- Go to FV Central > Operations > Laybacks > In Progress and create a folder using the standard naming convention.
Standard Naming Convention (LastFM_MyMovieTitle_YYYYMMDD_Layback)
Start with the capitalized full last name, then the capital first initial, followed by the capital middle initial. For example, if your name is Steven Paul Jobs: JobsSP.
Add an underscore, followed by an abbreviated project name without spaces. Capitalize each word of the project name or title. For example, if your project name is My Movie: JobsSP_MyMovie
Add another underscore, followed by the year, month, and day without spaces. For example, if the date is April 1, 1976: JobsSP_MyMovie_19760401
Supplemental information can be added after the date, such as version, audio, frame rate, or codec information. For example, if your file is version 2, with LtRt audio, at 24fps, and ProRes HQ codec: JobsSP_MyMovie_19760401_v02_LtRt_24p_PRHQ. See the ISDCF website for more info.
Connecting to the Shared Database
- Launch DaVinci Resolve
- Click on the Show/Hide Database icon in the top left corner of the DaVinci project manager window.

3. Click on Connect Database.

4. In the Connect Database window that pops up, select the PostgreSQL tab, and enter in the following database credentials:
DB name: laybacks
location: 10.2.19.224
un: fvsound
Pw: LetMeIn!
Then click Connect Database.

Restoring from a Template Archive
- In order to choose the right template, you need to check the resolution and frame rate of the submitted video file first. Go to FV Central>Operations>Laybacks>Submissions and find the video file. Open it with quick time then press Command + I to open the video inspector window. Take note of the resolution and frame rate.
You will need to use 4K templates for the following resolutions:
4K DCI:4096 x 2160
4K UHD: 3840 x 2160

2. Navigate to the Year > In Progress folder in the resolve database, double-clicking to open each folder. Right click anywhere and choose Restore Project Archive.

3. Navigate to FV Central>Operations>Layback>Templates and choose the template that has the same frame rate and resolution (4K or HD) as the project you are working on.

Once the project is in the Resolve Project Manager, right click and rename the project using CalArts Standard naming convention.

3. Open the project. Navigate to the Media tab. In the Media Pool, you will have an Original Media folder and a template timeline. In the 4K template, you will have a 4K timeline for rendering 4K files and a HD timeline for rendering HD files.



Switch to the Media tab, right click in the Media Storage panel in the top left and click Add New Location. In the Finder window that opens, navigate to the FVCentral folder and click Open. This allows DaVinci Resolve to access media located on FVCentral.

4. Navigate to the top bar menu and select File> Import File > Import media …Find the student’s final video file in FVCentral > Submissions > Laybacks. Or you can navigate to the same folder in the Media tab and drag the file into the Media Pool directly.


Do not use the video file in the Pro Tools session unless explicitly told to. Confirm that the file is named correctly according to the standard naming convention; rename it if needed.
5. Navigate to File> Import File > Import media … again to import the audio files into your project. Find the client’s mix folder at FVCentral > Operations >Mixes > Completed [Paid] or Completed [Unpaid]. Or you can navigate to the same folder in the Media tab and drag the file into the Media Pool directly.

Remember that the Mix files are not bounced, they are located inside the Audio Files folder within the Pro Tools folder structure. They are named according to CalArts naming conventions:
Mix Files :
UserJ_MyMovie_20181119_Mix_5,1_L
UserJ_MyMovie_20181119_Mix_5,1_R
UserJ_MyMovie_20181119_Mix_5,1_C
UserJ_MyMovie_20181119_Mix_5,1_LFE
UserJ_MyMovie_20181119_Mix_5,1_Ls
UserJ_MyMovie_20181119_Mix_5,1_Rs
UserJ_MyMovie_20181119_Mix_LtRt_L
UserJ_MyMovie_20181119_Mix_LtRt_R
UserJ_MyMovie_20181119_Mix_InternetOnly_L
UserJ_MyMovie_20181119_Mix_InternetOnly_R
You can check the Session Setup screenshot to confirm the sample rate, bit depth, and timecode of the session (48kHz, 24 bit, and 23.98 or 24 or 29.97 or 25).
6. Now all 10 audio files and the final image file with leader will be in your Media Pool. Toggle to List View to easily see the metadata for each file. You can check the frame rate of your video here again.

- 7. Put the imported media into the Original Media bin. Click on the name of your timeline to rename it as “UserJ_MyMovie_YYYYMMDD_Layback_Master_Headleader”

8. Press Command+S to save the project
Audio Configuration
- The audio channel configuration has to be assigned before they are used for the layback. For each mix file, select it and right click on the audio clip> clip attributes. Tip: you can click on the Clip Name column to display clips in alphabetical order.
- In the clip attributes window, navigate to the Audio tab.


2. In the format column, change the audio format to 5.1. In the source channel column, make sure all the channels except one is muted and Embedded in Channel 1 is selected for the appropriate channel.

3. For stereo files, select stereo format and similarly make sure only one channel is active while the other is muted.

4. Check the video file for audio in the same manner. Right-click on the video and select Clip Attributes. If there are any audio channels contained in the video, set them to Mute.
5. After all the channels have been configured, we can double-check the audio channel column, making sure that 5.1 channels show 6 and stereo channels show 2. Now is a good time to Save.

The Layback
Now we’re ready for the layback. Confirm the frame rate of the video file by checking in the Media tab columns.
For a 4K project you need to repeat the following steps in the 4K timeline as well.
- Navigate to the Edit Page. Double click on the Timeline that you just renamed to open it.


2. Drag and drop the video file you just imported onto the video track. If the Video contains audio, right click on it in the timeline and uncheck Link Clips. This will allow you to delete the audio without disturbing the image.

3. In the timeline, tracks A1 to A6 are for the 5.1 audio files in SMPTE order: L, R, C, LFE, Ls, Rs. Tracks A7 and A8 are for LtRt files. Tracks A9 and A10 are for InternetOnly files. Drag the audio files into the corresponding tracks.


The mix audio files each contain a tone and a vocal identifier for each channel so when you place them in the right order in the timeline you will see the waveforms stacked.
4. Check that the 2 occurs at 00:59:58:00. Zoom into the end of the project and see if the audio file needs to be trimmed. If there is a tail pop, check that it is in sync.

5. Now is a good time to save.
Trimming Head Leader
- Now we can get ready for final output. In the clip list, right click on our timeline > Duplicate to create a new timeline. Rename it UserJ_MyMovie_YYYYMMDD_Master. Double click on the timeline to open it in the edit window.

2. Trim off the head leader of the project. Enter 1:00:00:00 in the timecode and use the blade tool (or shortcut: shift + [ will trim to playhead).

Your timeline should then look like this:

3. Set your In and Out points on the timeline. The shortcut is I for In Point and O for Out Point. If there is not at least 1 second of black after 01:00:00:00, set In Point 1 at 00:59:59:00, and go to Effects Library>Generator and drag Solid Color to the beginning of the video and trim it down to 1 second. So, you should have 1 second of black screen at 00:59:59:00. Set Out Point at the end of Timeline.


4. If there is tail pop, it must be removed. The tail pop placement varies per project and removing it will require some timecode math. A tail pop occurs exactly 2 seconds after the last image and the place to cut will depend on the frame rate. To remove the tail pop, find the 2 and use the following table to determine how much to subtract from the timecode:

5. If there is not least 1 second of black before the end of the picture, add a 1-second slug.
If the project is4K, repeat the above steps in the 4K timeline.
Final Output:
- We will be creating 3 different Outputs:
- Surround (OriginalResolution/5.1),
- Internet (HD/Stereo)
- ArchivalMaster (Original Resolution/5.1+LtRt+Internet)
1. 5,1 Output
a) Go to the Deliver Tab. If original media is 4K, make the 5,1 Output select the 4K timeline in Edit Tab. In Deliver Tab, on the top left (you may need to scroll the bar to the left) Select FV_5,1 Render Preset.

b) Customize the file name: UserJ_MyMovie_YYYYMMDD__Resolution_5,1 and set Location to the folder on FVCentral Operations>Laybacks> InProgress>UserJ_MyMovie_YYYYMMDD_Layback
- c) Make sure the video and audio settings in the preset are as such. Customize Resolution to Original Media’s resolution and set Frame Rate to project’s frame rate.

d) Above the timeline, make sure you have In/Out Range selected as your Render range (not Entire Timeline).
e) Click Add to Render Queue at the bottom of the preset window.

2. Internet Output:
a) If the original media is 4k, go to Edit Tab and select HD timeline then come back to Deliver Tab. Then select FV_Internet Render Preset.
b) Make sure the video settings and audio settings are as such. Set Resolution to HD and customize frame rate to project’s frame rate.
c) Check the render range is still In/Out Range above the timeline.
d) Then click Add to Render Queue.

- Archival Master Output
a) If the project is 4K, select 4K timeline with headleader in Edit Tab then come back to Deliver Tab.
b) Check the settings are as such. Customize Resolution and Frame Rate to original media’s resolution and frame rate. Then click Add to Render Queue.
c) Check the render range is still In/Out Range above the timeline.
d) This file serves as video archive in the case that the DaVinci archive is somehow lost.

4. Select each job in the Render Queue and click Start Render to render each clip from the render queue.
Tidying Up
- Before tidying up, remember to save your project and close it first. Go to File > Project Manager, right click on your project, choose Export Project Archive.


Or you can go to Project Manager by clicking at the house icon at the bottom right of the window.

2. Then choose the folder you want to save the project archive in: FVCentral >Operations> Laybacks > Completed PAID or IN Progress>UserJ_MyMovie_YYYYMMDD. It will save as a .DRA (DaVinci Resolve Archive) file. The Archive window will pop up. Leave the default settings and click OK to finish archiving. Resolve will copy all of the media used in your project into a new folder with the master layback folder.

Once you’ve finished archiving your project, move the entire layback folder to the appropriate Completed folder on FVCentral > Operations > Laybacks.
To move your DaVinci Resolve project into the Completed folder, open Project Manager, navigate to the In Progress folder. Right click on your project> Cut.

7. Then Navigate to the Completed folder and right click > Paste. Now your project has been moved.

Appendix
Reopening Projects
Although databases do not contain media, they do contain all of the metadata for every project. They also contain all of the timelines for every project you have worked on.
When you open the DaVinci Resolve project file (.drp), your audio and video files within the project may not be automatically relinked. To relink your media: select all clips that need to be relinked, right click > relink selected clips… > navigate to the correct project folder. (Make sure you add FVCentral as a storage location so that Resolve can access all required media.)

Creating Blu-ray Assets in Compressor
We don’t typically create Blu-ray and DVD assets by default but we can provide them upon request from students.
- Create a new subfolder within the student’s layback folder called Bluray & DVD Assets.
- Right click on the 5.1 video file > Open With > Compressor

3. Once Compressor is open, click to select the appropriate template (depending on what the student has requested) from the left panel and drag this on top of the video file.

4. You can select and drag multiple templates onto the video file to cue up more than one job.
5. Right click on Source, go to location>other to choose the destination of your folder, put the file into the Blu-Ray & DVD folder that you created.


6. Click on Start Batch.

7. Compressor will now process the files and save them at the location you designated.
